Linux 禁用通配符扩展以使Bash脚本不工作

当我试图阻止通配符扩展到以下脚本时，它不起作用。例如，在shell I类型中：（我还尝试了\*.m，“*.m”）

我得到

$ myDirectory
$ file1.m file2.m file3.m
$ find: paths must precede expression
$ Usage: find [-H] [-L] [-P] [path...] [expression]
$ 0 #The result of my function. Found 0 .m files. Should be 3.

getLargeNumFiles.sh

#!/bin/bash
# Syntax
# getLargeNumFiles [folderPath][ext]
# [folderPath] The path of the folder to read.
#   To use at folder to search: $(pwd)

function largeRead()
{   
    numFiles=0
    while read line1; do
        #echo $line1
        ((numFiles++))
    done
    echo $numFiles
}
folderPath=$1
ext=$2

echo $folderPath
echo $ext

find $folderPath -name $ext | largeRead

---

将变量放在引号中，以防止变量展开后进行通配符展开：

find "$folderPath" -name "$ext" | largeRead

find "$folderPath" -name "$ext" | largeRead
